I renamed some units, give me your toughts.

Not a fan of these names.
I’m not a fan either, sorry to say. I feel it makes them overly generic. Reminds me of modern day simplifications in user interfaces everywhere that do a “one style fits all” approach, where all icons become basic white or largely colorless stenciled icons used for every touch-point, which seems a little lazy. Your renamed units could be used in any medieval game anywhere, just plug and play… nothing special about them in terms of AoE uniqueness. They essentially answer the question: “Are your generic horse units basic, mean, angry, or super-angry?”, imo
Which is similar to AoE4’s UI where tech progression is a simple dot symbol system mini-game for me. How strong are your horses? Just look at the generic horse icon and see how many dots it has. “My horses are currently only 2 dots, therefore I must research to make 3 dots… and then 4 dots.” I pursue non-immersive dots rather than unique horse units, which is not fun for me. Same for most every other tech in AoE4, tbh. Its UI is one major reason I rarely play it, and don’t really want to play it. And I don’t want to see AoE2 draw inspiration from that more generic system
Ew, no. I’d rather call them “Light Cavalry”, “Light Cavalry”, and “Light Cavalry”; “Knight”, “Knight”, and “Knight”; and “Militia”, “Militia”, “Militia”, “Militia”, and “Militia”.
As a general rule of thumb, the less “Elite” and similar words are used the better. It’s honestly the best thing about Jian Swordsmen, they didn’t reuse “Elite” or “Heavy” or anything else because they didn’t need to. Which is also one of my reasons for not liking Champi Warriors: could they not have come up with one more name? How can a ship be “Elite” or how does making a Scorpion “Heavy” make it better?
I agree, but a Heavy Scorpion does happen to sound pretty cool to me
I imagine a heavier, more solid/dense wood used for them. (Even if all Scorpions pretty much crumble when touched by a fingertip, lol)
